Letters Patent No. 101,885, dated April 12, 1870.

IMPROVEMENT m LUBRICATING- AZLES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern Be it known that I, MILO F. KELLOGG, ofPittsfield, in the county of Lorain and in the State of Ohio, haveinvented certain new and useful'Improvements in Lubricating Axles; anddo hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in so constructing. an axle forvehicles that it can be oiled or lubricated back of the hub withoutremoving the hub.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to deson'be itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a longitudinal vertical section and fi Figure 2 is across-section, taken through at as,

A represents the spindle, projecting from the end of the axle D, saidspindle having ofi'sets a and b at .its inner end.

On the upper side of the axle D, at its outer end, that is, back of theinner end of the spindle A, is a projection, E, having an oil-chamber,(1, within. the same, which is covered by a lid, f- A passage or groove,0, leads from said oil-chamber (I through the offsets a and b, followingthe spindle A on the top any desired distance.

The skein B, which is held on the spindle by the nut O, is at its innerend provided with an enlargement, G, which incloses the ofiset a, andforms a chamber, 71, between the offset b and said enlargement, as shownin fig. 1.

In the orifice or chamber 11 a brass cup may be screwed, so as. topermit the oil to flow onto the spindle as it is required.

It will be seen that by this arrangement it is-not necessary to removethe wheel to lubricate the axle.

Having thus fully described my invention,

What I claim as new, and desire .to secure by Letters Patent, is--- Thecombination of the spindle A with the projection E, chamber d, passagee, and ofl'sets a b, with the thimble B, with an enlargement, G, allsubstantially as set forth.

In testimony that I claim the foregoing, I have hereunto set my handthis 18th day of January, 1870.

M. F. KELLOGG.
